Abstract


Access to intelligent technology of sensors and actuators, monitoring, control and communication in industrial environments contributed to a significant increase of the demand for complex automation systems. Concomitantly, the presence of more efficient and effective computational resources promotes new technologies and new methodologies for control systems project. In this context, the basis of factors for a common point of view is the integration, flexibility and reuse of the elements that make up the system, i.e. hardware and software. This will be possible if only there are availability of standards and procedures. In this context, the IEC 61499 standard has provided subsidies that guide the project and development of production control systems with emphasis on modularization and a botton-up approach. However, the first challenge in the process modeling of such systems is the understanding, definition and sequencing of activities of the global processes that the system should control. Thus, the aim of this paper is to present a hybrid method based on global and local state representation to generate the control algorithm, represented by a derivative of the Petri net through the use of graphical tools for modeling.
